The present invention relates to a catheter connector configured to provide an escape location for a liquid medium trapped therein. The catheter connector includes a body having a proximal end and a distal end. The proximal end includes a proximal end port for mating communication with a fluid delivery device. The body defines a hollow interior extending from the proximal end to the distal end. In one embodiment, the catheter connector includes an insert configured within the hollow interior of the connector. The insert defines a bore therethrough that is configured to receive a catheter at least partially therein. Further, the bore includes an interior wall and an exterior wall defining a thickness therebetween. The interior wall includes at least one discontinuity. Thus, when the catheter is inserted through the bore, at least one cavity is formed by the catheter and the at least one discontinuity of the insert. The cavity is configured to collect a liquid medium within the catheter connector, thereby maintaining a secure connection between the catheter and the catheter connector. In another embodiment, the hollow interior of the catheter connector may be manufactured with at least one discontinuity so as to form a cavity configured to collect a liquid medium within the catheter connector.
